Letters Patent No. 112,826, dated March 21, 1871.

IMPROVEMENT iN .RAILWAYsHiF-r'lNe-Tnucxs.

The Schedule referred to in these Letters Patent and making'part of'lthe'same.

whom it may concern l Be it known that I, PATRICK HENRY MCWIL- LIAMs, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improve- 'fment in a Railway Transfer or Shifting-Truck; and I 'do' declare thatV the following is a true and accurate description thereof, reference being had to the accompanying sheets of drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure 1, sheet 1, is a perspective view of my truck complete.

Eigure 2 is the same, but with the platform and revolving rack removed.

Figure 3 is a perspective view of one of the lever-l bolsters, inverted. v AFigure 4, sheet 2, shows, in perspective, the construction of the under part of the truck. Figure ,5. is plan of the truck propel', with one bolster in place. v

The nature of this invention vrelates tothe coustructio'n. of a railway truck, which is so arranged that it may be run from one track to another, crossing it at right angles, therebyT dispensing with 4all turn-tables, transfer-tables, or their equivalents.

,The invention consists in-two trucks, one within and at right angles to the other, providednrespectively, with axles and wheels, and with a platform in conimom'and all arranged and connected in a peculiar' manner, for thepurpose of enabling either'truck to he zdepressed and support the load and otherv truck, as

more fully hereinafter set forth.

In the dravving- A .represents the' outer rectangular truck-frame,

having journalefl therein, near leach end, the axle B, carrying the flanged wheels O. The extremities of 'the axles do not project outwardly from the sides of the frame. v L is the` inner truck-frame, in like manner provided with axles E and wheels F, but disposed at right angles to those of the outer frame, the wheels of both trucks being set to the same gauge. The' inner frame is so arranged as to play freely in a vertical direction between guides in the outer one.

G is a sill across the center of the'inner truck, extending beyond its sides, in line with the longitudinal centerof the outer one.

a are socket-pieces in the end corners of the outer frame, and b are bearings at the corners of the inner frame, in line with them.

H are lever-holsters, having arms or levers-c curved to clear the wheels G, andwhose ends are inserted :under the socket-pieces a, their main portions resting upon the bearings b, as shown in gs. 1 and 2.

A pair ofstrong bolts, I, sliding insnitable guides, is placedacross each end beam of the outer frame, the bolts of each pair being pivoted to, and operated simultaneously by, a lever, I.

J are lifting-levers, four in number, each being 'piv oted to a fulcrum, K, on the side-beams of' the outer frame, their outer ends projecting beyond the ends of the bea'ms, so that the bolts l may be shot out above or below them.

With the inner end of each lever a lug, L,'project follows, premisingthat the various parts are in the.

position shown in figa 1 and 2 In this position the trnck,'with its load, bearsupon f` l the wheels .O of the outer truck-frame, consequently will travel upon a line of rails parallel with sai wheels. N ow, if it be desired to transfer the load Ato Y aline of Iailscrossing the first track-at right'angles, the car or truck is stopped with the wheels 'over the crossing rails; then, by means ofthe leversv I', thebplts I are withdrawn from above the levers when the inner truck will no' longer be held up. by them.

Theweight of the load, acting upon the bearings b of the inner frame, through the bolster-levers,'forcesg .said inner frame down and the outer one up. f'lhev truck can now be run off upon the second or crossing line of rails. In this last' position of the various parts, to transfer the truck again, the attendants in sert the end of a handspilre under the end of the sill Gof the inner frame, making a fulcrum of the outer' one, when, by bearing down on the` hands'pilke, the

inner truck may-be raised and secureiby the bolts I, operating uponoue end at a' time; or, if the load be very heavy, two handspikes maybe usedyf inserting them in and operating-the levers J simultaneously. y

For greater convenience in moving about with long timbers or other 'material inrluniber-yards, depotgrounds, and in similar locations where the alleys or spaces in which the tracks are laid are narrow, I provide the truck with a revolving rack, N, shown in fig. 1; .This rack is pivoted by a central king-bolt to the platform M, ahy lateral motion in the rack being overcome byside-blocks e on the platform under the rack.

The rack is provided with rollers,f, underneath, traveling on theV platform, supporting the rack in yits fulerums K, the levers Vend I', anda bolts I, all constructed substantially as described and shown, for the purpose of enabling either truck to be depressed and support the other tmok and platform M, or heele? vatedfand be supported in turn.
